Attribution-ShareAlike 4.0 International Public License ("Public License"). To 
the extent this Public License may be interpreted as a contract, You are 
granted the Licensed Rights in consideration of Your acceptance of these terms

Section 1 - Definitions.

   Adapted Material means material subject to Copyright and Similar Rights that 
is derived from or based upon the Licensed Material and in which the Licensed 
Material is translated, altered, arranged, transformed, or otherwise modified 
in a manner requiring permission under the Copyright and Similar Rights held by 
the Licensor. For purposes of this Public License, where the Licensed Material 
is a musical work, performance, or sound recording, Adapted Material is always 
produced where the Licensed Material is synched in timed relation with a moving 
image.

Rights in Your contributions to Adapted Material in accordance with the terms 
and conditions of this Public License.
   BY-SA Compatible License means a license listed at 
creativecommons.org/compatiblelicenses, approved by Creative Commons as 
essentially the equivalent of this Public License.
   Copyright and Similar Rights means copyright and/or similar rights closely 
related to copyright including, without limitation, performance, broadcast, 
sound recording, and Sui Generis Database Rights, without regard to how the 
rights are labeled or categorized. For purposes of this Public License, the 
rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
   Effective Technological Measures means those measures that, in the absence 
of proper authority, may not be circumvented under laws fulfilling obligations 
under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, 
and/or similar international agreements.
   Exceptions and Limitations means fair use, fair dealing, and/or any other 
exception or limitation to Copyright and Similar Rights that applies to Your 
use of the Licensed Material.
   License Elements means the license attributes listed in the name of a 
Creative Commons Public License. The License Elements of this Public License 
are Attribution and ShareAlike.
   Licensed Material means the artistic or literary work, database, or other 
material to which the Licensor applied this Public License.
   Licensed Rights means the rights granted to You subject to the terms and 
conditions of this Public License, which are limited to all Copyright and 
Similar Rights that apply to Your use of the Licensed Material and that the 
Licensor has authority to license.
   Licensor means the individual(s) or entity(ies) granting rights under this 
Public License.
   Share means to provide material to the public by any means or process that 
requires permission under the Licensed Rights, such as reproduction, public 
display, public performance, distribution, dissemination, communication, or 
importation, and to make material available to the public including in ways 
that members of the public may access the material from a place and at a time 
individually chosen by them.
   Sui Generis Database Rights means rights other than copyright resulting from 
Directive 96/9/EC of the European Parliament and of the Council of 11 March 
1996 on the legal protection of databases, as amended and/or succeeded, as well 
as other essentially equivalent rights anywhere in the world.
   You means the individual or entity exercising the Licensed Rights under this 
Public License. Your has a corresponding meaning.

Section 2 - Scope.

   License grant.
      Subject to the terms and conditions of this Public License, the Licensor 
hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, 
irrevocable license to exercise the Licensed Rights in the Licensed Material to:
         reproduce and Share the Licensed Material, in whole or in part; and
         produce, reproduce, and Share Adapted Material.
      Exceptions and Limitations. For the avoidance of doubt, where Exceptions 
and Limitations apply to Your use, this Public License does not apply, and You 
do not need to comply with its terms and conditions.
      Term. The term of this Public License is specified in Section 6(a).
      Media and formats; technical modifications allowed. The Licensor 
authorizes You to exercise the Licensed Rights in all media and formats whether 
now known or hereafter created, and to make technical modifications necessary 
to do so. The Licensor waives and/or agrees not to assert any right or 
authority to forbid You from making technical modifications necessary to 
exercise the Licensed Rights, including technical modifications necessary to 
circumvent Effective Technological Measures. For purposes of this Public 
License, simply making modifications authorized by this Section 2(a)(4) never 
produces Adapted Material.
      Downstream recipients.
         Offer from the Licensor - Licensed Material. Every recipient of the 
Licensed Material automatically receives an offer from the Licensor to exercise 
the Licensed Rights under the terms and conditions of this Public License.
         Additional offer from the Licensor - Adapted Material. Every recipient 
of Adapted Material from You automatically receives an offer from the Licensor 
to exercise the Licensed Rights in the Adapted Material under the conditions of 
the Adapter's License You apply.
         No downstream restrictions. You may not offer or impose any additional 
or different terms or conditions on, or apply any Effective Technological 
Measures to, the Licensed Material if doing so restricts exercise of the 
Licensed Rights by any recipient of the Licensed Material.
      No endorsement. Nothing in this Public License constitutes or may be 
construed as permission to assert or imply that You are, or that Your use of 
the Licensed Material is, connected with, or sponsored, endorsed, or granted 
official status by, the Licensor or others designated to receive attribution as 
provided in Section 3(a)(1)(A)(i).

   Other rights.
      Moral rights, such as the right of integrity, are not licensed under this 
Public License, nor are publicity, privacy, and/or other similar personality 
rights; however, to the extent possible, the Licensor waives and/or agrees not 
to assert any such rights held by the Licensor to the limited extent necessary 
to allow You to exercise the Licensed Rights, but not otherwise.
      Patent and trademark rights are not licensed under this Public License.
      To the extent possible, the Licensor waives any right to collect 
royalties from You for the exercise of the Licensed Rights, whether directly or 
through a collecting society under any voluntary or waivable statutory or 
compulsory licensing scheme. In all other cases the Licensor expressly reserves 
any right to collect such royalties.

Section 3 - License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following 
conditions.

   Attribution.

      If You Share the Licensed Material (including in modified form), You must:
         retain the following if it is supplied by the Licensor with the 
Licensed Material:
            identification of the creator(s) of the Licensed Material and any 
others designated to receive attribution, in any reasonable manner requested by 
the Licensor (including by pseudonym if designated);
            a copyright notice;
            a notice that refers to this Public License;
            a notice that refers to the disclaimer of warranties;
            a URI or hyperlink to the Licensed Material to the extent 
reasonably practicable;
         indicate if You modified the Licensed Material and retain an 
indication of any previous modifications; and
         indicate the Licensed Material is licensed under this Public License, 
and include the text of, or the URI or hyperlink to, this Public License.
      You may satisfy the conditions in Section 3(a)(1) in any reasonable 
manner based on the medium, means, and context in which You Share the Licensed 
Material. For example, it may be reasonable to satisfy the conditions by 
providing a URI or hyperlink to a resource that includes the required 
information.
      If requested by the Licensor, You must remove any of the information 
required by Section 3(a)(1)(A) to the extent reasonably practicable.
   ShareAlike.

   In addition to the conditions in Section 3(a), if You Share Adapted Material 
You produce, the following conditions also apply.
      The Adapter's License You apply must be a Creative Commons license with 
the same License Elements, this version or later, or a BY-SA Compatible License.
      You must include the text of, or the URI or hyperlink to, the Adapter's 
License You apply. You may satisfy this condition in any reasonable manner 
based on the medium, means, and context in which You Share Adapted Material.
      You may not offer or impose any additional or different terms or 
conditions on, or apply any Effective Technological Measures to, Adapted 
Material that restrict exercise of the rights granted under the Adapter's 
License You apply.

Section 4 - Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to 
Your use of the Licensed Material:

   for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, 
reuse, reproduce, and Share all or a substantial portion of the contents of the 
database;
   if You include all or a substantial portion of the database contents in a 
database in which You have Sui Generis Database Rights, then the database in 
which You have Sui Generis Database Rights (but not its individual contents) is 
Adapted Material, including for purposes of Section 3(b); and
   You must comply with the conditions in Section 3(a) if You Share all or a 
substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace 
Your obligations under this Public License where the Licensed Rights include 
other Copyright and Similar Rights.

Section 5 - Disclaimer of Warranties and Limitation of Liability.

   Unless otherwise separately undertaken by the Licensor, to the extent 
possible, the Licensor offers the Licensed Material as-is and as-available, and 
makes no representations or warranties of any kind concerning the Licensed 
Material, whether express, implied, statutory, or other. This includes, without 
limitation, warranties of title, merchantability, fitness for a particular 
purpose, non-infringement, absence of latent or other defects, accuracy, or the 
presence or absence of errors, whether or not known or discoverable. Where 
disclaimers of warranties are not allowed in full or in part, this disclaimer 
may not apply to You.
   To the extent possible, in no event will the Licensor be liable to You on 
any legal theory (including, without limitation, negligence) or otherwise for 
any direct, special, indirect, incidental, consequential, punitive, exemplary, 
or other losses, costs, expenses, or damages arising out of this Public License 
or use of the Licensed Material, even if the Licensor has been advised of the 
possibility of such losses, costs, expenses, or damages. Where a limitation of 
liability is not allowed in full or in part, this limitation may not apply to 
You.

   The disclaimer of warranties and limitation of liability provided above 
shall be interpreted in a manner that, to the extent possible, most closely 
approximates an absolute disclaimer and waiver of all liability.

Section 6 - Term and Termination.

   This Public License applies for the term of the Copyright and Similar Rights 
licensed here. However, if You fail to comply with this Public License, then 
Your rights under this Public License terminate automatically.

   Where Your right to use the Licensed Material has terminated under Section 
6(a), it reinstates:
      automatically as of the date the violation is cured, provided it is cured 
within 30 days of Your discovery of the violation; or
      upon express reinstatement by the Licensor.
   For the avoidance of doubt, this Section 6(b) does not affect any right the 
Licensor may have to seek remedies for Your violations of this Public License.
   For the avoidance of doubt, the Licensor may also offer the Licensed 
Material under separate terms or conditions or stop distributing the Licensed 
Material at any time; however, doing so will not terminate this Public License.
   Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 - Other Terms and Conditions.

   The Licensor shall not be bound by any additional or different terms or 
conditions communicated by You unless expressly agreed.
   Any arrangements, understandings, or agreements regarding the Licensed 
Material not stated herein are separate from and independent of the terms and 
conditions of this Public License.

Section 8 - Interpretation.

   For the avoidance of doubt, this Public License does not, and shall not be 
interpreted to, reduce, limit, restrict, or impose conditions on any use of the 
Licensed Material that could lawfully be made without permission under this 
Public License.
   To the extent possible, if any provision of this Public License is deemed 
unenforceable, it shall be automatically reformed to the minimum extent 
necessary to make it enforceable. If the provision cannot be reformed, it shall 
be severed from this Public License without affecting the enforceability of the 
remaining terms and conditions.
   No term or condition of this Public License will be waived and no failure to 
comply consented to unless expressly agreed to by the Licensor.
   Nothing in this Public License constitutes or may be interpreted as a 
limitation upon, or waiver of, any privileges and immunities that apply to the 
Licensor or You, including from the legal processes of any jurisdiction or 
authority.
